3.24
Hydraulic slide bolt and conveyor system fulfil the following function in trailer:
•
raising / lowering folded conveyor,
•
locking / unlocking folded conveyor,
•
opening / closing container channels slide.
IMPORTANT!
Remember the setting of both valves simultaneously during work.
Connecting individual circuits for work takes place manually by the machine operator with the
aid of hydraulic valves (4) – figure (3.19), placed on bracket. Valve set in position 1 directs
hydraulic oil stream to cylinders (1) and (2). In the event of setting valves in position 2, oil is
directed to circuit controlling slide cylinder. In central position, the supply of hydraulic oil to
system is cut off.
Hydraulic system quick couplers are marked with the aid of red stoppers, as stated on
information decal (8). Working positions of valves are marked on information decal (9).
3.12 HYDRAULIC CLUTCH SYSTEM
Hydraulic clutch system is designed for remote starting of trailer container auger conveyor
drive. Position of system elements is shown in figure (3.20).
With regard for the significant differences in the design of agricultural tractors (supply
pressure from hydraulic manifold), conduct reduction valve adjustment after connection to
tractor. If not, the hydraulic clutch may be damaged.
IMPORTANT!
After connecting agricultural tractor trailer regulate the reduction valve (1) – figure (3.20).
